LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 315,627, dated April14, 1885,

Application filed September 10, i884. (No model.) Patented in DenmarkOctober 23, 1882, No. 738.

To aZZ- whom, it 71mg concern Be it known that we, NInLs J ACOBSEN andHans P. Jnnsnn, of Aarhus, in the Kingdom of Denmark, have inventedcertain new and useful Improvements in Lubricators; and we do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawing, which forms-a part of this specification, whichindicates a vertical sectional view of a centrifugal machine providedwith our improved lubricator.

Our invent-ion has relation to lubricators for centrifugal machines andother machines having vertical shafts; and it consists in the improvedconstruction and combination of parts of such a lubricator, by means ofwhich the oil which is used for oiling the upper bearing of the shaftmay pass down and lubricate the step for the shaft, whereupon it willpass out of the step and be again carried up to the upper bearing, thusutilizing the oilorlubricant continually, and forming a continuous flowof lubricant through the bearings, which will effectually cool them, therapid revolutions of the said shaft necessitating a very copious andconstant lubrication, as will be hereinafter more fully described andclaimed.

In the accompanying drawing, the letter A indicates the drive-shaft,which is journaled in the upper bearing, B, and rests and turns with itslower end in a step, 0.

D is an oil-cup, provided with an outlet tube, E, and placed above theupper bearing,

down upon the shaft, and a cup or casing, G, is secured under thehearing, and is provided with a central upwardly-projecting flange, H,which bears closely against the shaft and turns the oil running downtheshaft into the bottom of the casing, from which it is carried througha pipe, I, down to the cup J, formed at the upper end of the step. Fromthis cup the oil passes down the lower end of the shaft into a cavity,K, at the bottom of the step, from which cavity a pipe, L, passes out ofthe step, which pipe may be provided with suitable means for raising theoil up into the oil-cup, allowing it to pass down again, and thuslubricate the bearing and step continuously.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States- In a lubricator for verticalshafts, the combination of the upper bearing having the cup at its upperend and formed with a tube or conduit opening from the lower end of thebearing into the cup, the oil-cup having the outlet-tube opening intothe conduit in the bearing, the casing at the lower end of the bearing,having the central upwardly-projecting flange, the pipe leading fromthis casing, the lower step formed with a cup at its upper end and witha cavity at its bottom, and the outlet-pipe, as and for the purposeshown and set forth.

In testimony that we claim the foregoing as our own we have hereuntoaffixed our signatures in presence of two witnesses.
